SAP/Oracle RMAN /init<SID>.sap - rman_proxy

I am using NetBackup and Oracle RMAN.

What should the variable rman_proxy (in init<SID<.sap) be set to?

It defaults to 'no'.

Should I change it to yes? and why?

    Hi William,

    you might check

    SAP" target="_blank">http://help.sap.com/saphelp_nw2004s/helpdata/en/0d/d3058d4a0c11d182b80000e829fbfe/frameset.htm">SAP DB Guide Oracle (BC-DB-ORA-DBA)

    There you'll find this explanation:

    This parameter defines that the proxy copy functionality is to be used by RMAN with an external backup library, that is, backup_dev_type = rman_util|rman_disk|rman_stage.

    Syntax: rman_proxy = no|yes|only

    Default: no

    Ok, so what does this mean?

    Looking into the Oracle Documentation we find this:

    "You can also use the [RMAN] BACKUP command to generate a proxy copy, which is a backup to a third-party medium in which the entire data transfer is conducted by a media manager."

    To conclude: if you don't yet know about this, you pretty sure don't need it. If your Backup/Restore Solution works for you - fine, keep it that way.

    The rman_proxy is pretty much a kind of "advanced" feature you might use, if you're sure that the Backup Software is much better in getting the files from an to the oracle data filesystem than rman is.

    Before you use this, you'll also want to talk to your Backup Software vendor, if the software can handle this and how.

    Best regards,

    Lars
